Ben Affleck plans to live on $1.50 per day for at least one day

The idea of anyone living on $1.50 a day is shocking. The idea of Oscar winner Ben Affleck doing it is near incomprehensible. But that's exactly what the actor has promised to do next week as part of the poverty-awareness campaign Live Below the Line, the non-profit announced. For at least one day, Affleck will keep all his food and drink costs below $1.50 to raise money for The Global Poverty Project. Joining the "Argo" star in the campaign are Sophia Bush, Josh Groban, Debi Mazar and Hunter Biden.

According to Live Below the Line's website, the purpose of the project is "to give a glimpse into the lives of 1.4 billion people who have no choice but to live below the line every day — and who have to make $1.50 cover a lot more than food."

Those participating are expected to tweet their experiences throughout next week on their personal Twitter accounts and on Live Below the Line's account (@LBLUS).
